RCF LF15G401 - 1600W 15-inch Ceramic Low-Frequency Driver with 4-inch Voice Coil and 8-Ohm Impedance in Black Finish

The RCF LF15G401 is a high-performance 15-inch ceramic low-frequency driver, designed to offer exceptional power handling and low distortion for demanding sound reinforcement applications. With a continuous program power handling of 1600W, the LF15G401 excels in producing deep, controlled bass frequencies while maintaining clarity and precision in high-output environments. The combination of a fiber-loaded cone assembly and a high-excursion triple-roll surround allows for a peak-to-peak excursion of 52mm, delivering remarkable strength and performance even at extreme levels.

The LF15G401 features a 4-inch copper voice coil, wound on a fiberglass former, which ensures efficient power handling while keeping the moving mass light for faster transient response. The driver's dual spider design, constructed with silicon-based damping control, provides excellent stability and minimizes distortion, ensuring smooth operation during large excursions. The straight cone geometry further improves the driver's efficiency, resulting in precise low-frequency reproduction with minimal distortion.

With a frequency range of 35 Hz to 1500 Hz and a sensitivity of 97 dB, the LF15G401 is capable of delivering powerful mid-bass and low-bass reproduction, making it ideal for a variety of professional audio applications, including subwoofer and mid-bass systems. The ceramic magnet structure provides a high power-to-weight ratio, ensuring that the LF15G401 can handle demanding low-frequency signals while maintaining a lightweight and durable design. Whether used for live sound reinforcement or installed in large audio systems, this driver offers exceptional performance and reliability.
